Question

What is the point slope form of a line with slope -4 that contains the point (-2.3)

Answer 1

Answer: y = -4x - 5

Explanation:

In order to find the equation, use the point-slope formula:

`\blacktriangleright\quad\pmb{y-y_1=m(x-x_1)}`

Plug in the values:

`\blacktriangleright\quad\pmb{y-3=-4(x-(-2)}`

`\blacktriangleright\quad\pmb{y-3=-4(x+2)}`

Convert to slope intercept

`\blacktriangleright\quad\pmb{y-3=-4x-8}`

`\blacktriangleright\quad\pmb{y=-4x-5}`
